I'm working on blood flow simulation with FSI condition. Actually right now i have doubt about my result because my solving time duration is to short, for example about 20 minutes. Many times ago i had such this simulation and its solving time duration was approximately 3 hours with i7 CPU.

I should say right now i'm working with Ansys12 and i'm using CFX mesh but before i used Ansys13 and Ansys meshing.

Actually i took results for fluid and solid . for example i found out Von Misses stress for solid part and also different contour for pressure and velocity and it was acceptable bud for example i can not catch good streamline for velocity.
